Seems like you anti-mosque folks would want this thing getting built. After all, is the goal to make them waste money on erecting silly structures to their particular mythology, just like you christian types? Or is this simply a "my mythology is better than yours" pissing contest?
Normally I adopt a 'live and let live' attitude towards religion, but this stupid issue keeps resurfacing enough that I decided to exercise my freedom of speech and call it like it is - a stupid issue. How about they build whatever they like, you build whatever you like, and we call it a day? Let them build their silly structure at ground zero, and you guys build one there, too. Or both of you don't build there, and we can use the space to throw in a nice restaurant, a library, or some condos - you know, something that we can all use. If you two religions can't play nice with one another and get along, maybe neither of you should be anywhere near ground zero.
